Connecting a TV to a receiver without HDMI usually comes down to matching whatever legacy port your receiver actually has — optical (TOSLINK), RCA composite/analog, or coaxial digital — to the corresponding output on your TV, because most TVs still include at least one of these even after they dropped RCA-in years ago. In a 12x16ft living room with a 15-year-old Yamaha receiver, I’ve had the best luck starting with optical, then falling back to RCA when the TV lacks a digital audio out.
If you’ve inherited an older receiver — the kind with a faceplate full of RCA jacks and zero HDMI ports — you’re not alone. This shows up constantly on forums like r/hometheater and r/techsupport: someone’s father-in-law switches from a cable box to a streaming device, keeps the old Yamaha or Sunfire receiver because it still sounds great, and then discovers the new TV or streaming box has nothing but HDMI outputs. The fix isn’t complicated, but it does depend on exactly which ports you’re working with on both ends, and getting the cable spec wrong is where most people waste money.
Direct Answer: How to Connect a TV to a Receiver Without HDMI
Check your TV for an optical audio out (TOSLINK), a 3.5mm headphone/audio jack, or RCA composite outputs — most TVs made after 2010 still include at least one. Run a cable matching that port to the corresponding input on your receiver (optical-to-optical, RCA-to-RCA, or 3.5mm-to-RCA with an adapter), then select that input on your receiver’s source menu.
Step 1: Identify What Ports You Actually Have
Before buying anything, get on your knees and look at both the back of the TV and the back of the receiver. This sounds obvious, but I’ve seen people buy an HDMI-to-RCA converter when their TV had a perfectly good optical output the whole time.
On the TV side, look for:
- Optical audio out (TOSLINK) — small square port, usually labeled “Digital Audio Out” or “Optical”
- RCA audio out — red/white analog stereo pair, occasionally still found on TVs marketed toward budget or hospitality use
- Coaxial digital audio out — looks like a standard RCA jack but carries a digital signal, not analog
- 3.5mm headphone jack — increasingly common as the last analog fallback on newer TVs
On the receiver side, check for the reverse of whatever you found on the TV — a matching optical in, RCA stereo in, or coaxial digital in. If your receiver only has speaker-level inputs and no line-level RCA or digital inputs at all, you’re dealing with a genuinely pre-HDMI, pre-digital unit, and your options narrow to RCA analog or a Bluetooth transmitter workaround.
One Reddit thread I came across (r/audio) involved someone whose inherited receiver had no HDMI and no obvious digital input — they ended up running a 3.5mm-to-RCA cable successfully, but lost surround processing entirely because the receiver was only getting a stereo-down analog feed. That’s the tradeoff worth understanding upfront: analog RCA gets you sound, not necessarily the surround channels your receiver is capable of decoding.
Step 2: Match the Cable to the Port — Not the Other Way Around
This is where most guides get vague, so here are the actual cable types and what they do:
Optical (TOSLINK) cable — carries a digital multi-channel signal (up to 5.1 in most cases, depending on TV output). This is generally the best-sounding option if both devices support it, since it preserves more of the original audio format than a downmixed analog RCA connection. TOSLINK cables run $6-15 for a 6ft length and don’t require any adapter — it’s a direct 1:1 connection.
RCA composite/stereo cable — carries analog stereo audio (and composite video, if your setup needs it). This is the most universal option because it’s been standard since the 1980s, but it’s stereo-only; you will not get discrete surround channels through a basic RCA hookup.
Coaxial digital cable — visually identical to RCA but carries a digital bitstream. Don’t mix this up with analog RCA — plugging an analog RCA cable into a coaxial digital input (or vice versa) won’t damage anything, but you’ll get no sound or garbled static.
3.5mm-to-RCA adapter cable — needed when your TV’s only audio out is a headphone-style jack. This converts analog signal to the RCA input on your receiver.
Who it’s for: Anyone with an older receiver that only has RCA stereo inputs and a TV or source device that still outputs RCA composite — this is the simplest, cheapest fix for a straightforward analog hookup.
Who should look elsewhere: If you want discrete 5.1 surround sound out of your TV’s audio, this cable won’t get you there since it’s stereo-only analog; you’d need optical or coaxial digital instead.
Who it’s for: Budget-conscious buyers doing a one-time analog hookup between an old TV output and receiver, where sound quality beyond basic stereo isn’t the priority.
Who should look elsewhere: If you’ve had reliability issues with cheaper composite cables before, the RCA cable above with the higher rating is a safer bet for a connection you don’t want to troubleshoot again in six months.
Step 3: Handle the Coaxial-to-RCA Mismatch (If Applicable)
If your TV outputs coaxial digital audio but your receiver only has RCA analog inputs (or vice versa), you need a format-matching adapter — not just a cable swap. This is a more common mismatch than people expect, especially with receivers built in the analog-only era before digital coax became standard.
Who it’s for: People dealing with a physical connector mismatch — F-type coax connector on one end, RCA-style jack on the other — where the underlying signal type is already compatible.
Who should look elsewhere: If you actually need to convert a digital coaxial signal into an analog signal your old receiver can decode, you need a dedicated digital-to-analog converter box, not just a connector adapter — this product bridges connector shapes, not signal formats.
Step 4: If All Else Fails — RCA to HDMI Converter (Reverse Scenario)
Sometimes the actual gap runs the other direction — your source has only HDMI out, but your receiver has no HDMI in at all. In that case, you need a converter box that takes HDMI in and outputs RCA/composite on the other side.
Who it’s for: Anyone whose actual bottleneck is a source device (streaming stick, game console, cable box) that only outputs HDMI, paired with a legacy RCA-only receiver.
Who should look elsewhere: If your problem is TV audio out to receiver (not source-to-receiver), this converter solves the wrong direction of the problem — you want a TOSLINK or RCA cable straight from the TV’s audio out instead.
A cautionary note on the reverse-direction product — the passive HDMI-to-RCA cable:
Who it’s for: Genuinely niche cases where you need a physical adapter between ports that already carry compatible signal types — not an actual HDMI-to-analog conversion.
Who should look elsewhere: If you need real HDMI-to-RCA signal conversion, get the active Tengchi converter above instead — this passive cable will leave you with no picture and no sound despite the product name suggesting otherwise.
Step 5: Set Levels and Confirm the Connection Actually Works
Once the cable is run, don’t just assume it’s working because there’s sound. A few numbers worth checking:
- Input selection: On the receiver, manually select the correct analog or digital input — auto-detection often fails on older RCA/coax setups, unlike HDMI’s handshake protocol.
- Volume matching: TVs typically output line-level audio around -10dBV; if your receiver’s input is calibrated for a different reference level, you may need to adjust the receiver’s input trim by 3-5dB to avoid clipping or a too-quiet signal.
- Channel level check: If you’re running a basic 2-channel stereo connection (RCA), don’t expect your receiver’s Audyssey, YPAO, or similar auto-calibration to do anything useful — those systems calibrate multi-channel speaker output, not a stereo-downmixed input source. Auto-calibration on the speaker side still matters (a typical Audyssey run takes about 6-8 minutes and can correct a 2-3dB front L/R imbalance), but it won’t fix a mono-sounding TV feed if the actual problem is the input cable.
- Sync/lip-sync delay: Analog RCA connections sometimes introduce a slight audio delay relative to picture (a few hundred milliseconds isn’t uncommon on older gear) that TOSLINK usually avoids — if dialogue seems out of sync, check your receiver’s audio delay/lip-sync setting first before assuming the cable is faulty.
In my own setup with a Denon receiver from the pre-Atmos era, going optical instead of RCA analog made a noticeable difference — dialogue was tighter and I didn’t need to touch the lip-sync offset at all. On the RCA-only backup connection, I had to dial in about a 100ms delay adjustment to get picture and sound aligned again.
Wireless Alternatives (When Cables Aren’t an Option)
You can connect a TV to a receiver wirelessly, but not directly through any built-in feature on either the TV or a typical legacy receiver — you’ll need a Bluetooth transmitter plugged into the TV’s audio out, paired with either a Bluetooth-receiving dongle on the receiver’s RCA input or a receiver with built-in Bluetooth. Expect noticeable audio latency (often 100-300ms) with budget transmitters, which is usually fine for casual TV watching but distracting for anything requiring tight lip-sync, like fast dialogue or sports commentary. If you’re already troubleshooting Bluetooth pairing issues on a Denon receiver specifically, the process and common failure points are covered in more detail in our Denon Bluetooth pairing guide.
When You Should Just Upgrade the Receiver Instead
If you’re stringing together three adapters and still not getting proper surround sound, it might be time to stop patching an analog-only receiver. A receiver with modern HDMI ARC/eARC support handles the same TV-audio problem with a single cable and full multi-channel passthrough — no downmixing, no adapters, no lip-sync guesswork.

Frequently Asked Questions
How do I get my TV to play through my receiver?
Connect your TV’s audio output — optical, RCA, or coaxial digital — to the matching input on your receiver, then select that input on the receiver’s source menu. If your TV has HDMI ARC/eARC and your receiver supports it, a single HDMI cable is simpler and preserves more audio channels than any analog workaround.
How do I connect my old receiver to my smart TV?
Check your smart TV for a digital audio out (optical or coaxial) or a headphone/RCA analog out, then run a matching cable to your old receiver’s corresponding input. Most smart TVs retain at least one legacy audio output even though HDMI has become the primary connection method for video and multi-channel audio.
What should I do if my TV has no HDMI ARC port?
Use your TV’s optical audio output if it has one — it carries multi-channel digital audio without needing ARC. If there’s no optical port either, fall back to the TV’s RCA or 3.5mm analog output, understanding you’ll get stereo sound rather than discrete surround channels.
Can you connect a TV to a receiver wirelessly?
Yes, using a Bluetooth audio transmitter plugged into the TV’s audio out, paired with a Bluetooth receiver or dongle connected to your receiver’s RCA input. Expect some audio latency (often 100-300ms) compared to a wired connection, which matters more for fast-paced content than casual viewing.
Does RCA cable support surround sound from a TV?
No — a standard 2-channel RCA connection only carries stereo audio, not discrete 5.1 or 7.1 surround channels. To get real surround sound from a TV without HDMI, you need optical (TOSLINK) or coaxial digital, both of which can carry a compressed multi-channel bitstream that your receiver’s decoder can process.
Why does my receiver show no sound after connecting RCA cables?
Check that you’ve selected the correct analog input on the receiver — auto-detection generally doesn’t work on RCA connections the way it does with HDMI. Also confirm you haven’t mixed up a coaxial digital port with a standard analog RCA port, since they look identical but carry incompatible signal types.
Is optical or RCA better for connecting a TV to a receiver?
Optical (TOSLINK) is generally the better choice when available, since it carries a digital multi-channel signal rather than the stereo-only analog signal RCA provides. RCA remains useful as a fallback when a TV has no digital audio output at all, but expect a stereo downmix rather than full surround separation.
Can I use a 3.5mm headphone jack to connect my TV to a receiver?
Yes, with a 3.5mm-to-RCA adapter cable running from the TV’s headphone/audio-out jack to your receiver’s RCA input. This delivers analog stereo sound only, and volume levels can vary depending on whether the TV’s headphone jack outputs a fixed or variable signal — check your TV’s audio settings if levels seem inconsistent.
